This is answered comprehensively here. Beside this, do weaves make your hair grow?
Using Sew-In Weaves to Grow Longer Hair. Hair weaves can do much more than make your hair look longer and thicker. Wearing a weave is also a smart way to protect your hair if you're trying to gain length. Protective styles take many forms, whether your hair is natural, relaxed or texturized.
Secondly, how long should you keep a weave in your hair? “The recommended length of time to keep a weave in is two months," says Charlotte. "Full head weaves and tracks should be touched up every 2 to 4 weeks. You should also leave a 2 to 4 week gap in-between weaves and it's essential to have conditioning treatments done before, during and after your weave,” she adds.
Similarly, you may ask, does weave stop hair growth?
Wearing certain types of weave back to back (braids, pinned in ponytails and sew-ins) can stress out your hair. Your hair also wears thin because your arrector pili muscle (what holds your hair at the scalp) is destroyed or goes dormant, both of which can stop hair growth.
Is a Sew In bad for your hair?
Sew in, just like any other weave, has its ups and downs. They can protect your hair but if not “installed” correctly it can damage or break your hair. If you're trying to grow your hair out it's recommended that you install a “full head” of weave (which means none of the clients hair is left out.).
